connection appropriate for this monitor. For information on the correct power cord set to use with the
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.
• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.
• Disconnect power from the product by unplugging the power cord from the electrical outlet.
For your safety, do not place anything on power cords or cables. Arrange them so that no one may
accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the

ergo and/or on the documentation CD, if one is included with the monitor.
CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for
the computer and its peripheral devices (such as a monitor, printer, scanner) to some form of surge
protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips
provide surge protection; the power strips must be specifically labeled as having this ability. Use a
power strip whose manufacturer offers a Damage Replacement Policy so you can replace the
equipment, if surge protection fails.
Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.
WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts may fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the LCD monitor so that they can not
be pulled, grabbed, or tripped over.
Maintenance Guidelines

●
Do not drop the monitor or place it on an unstable surface.
●
●
●
●
Do not allow anything to rest on the power cord. Do not walk on the cord.
Keep the monitor in a well-ventilated area, away from excessive light, heat or moisture.
When removing the monitor base, you must lay the monitor face down on a soft area to prevent
it from getting scratched, defaced, or broken.
Cleaning the Monitor
1. Turn off the monitor and unplug the power cord from the back of the unit.
2. Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.

Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
You are not using a standard graphics adapter.
You are not using a preset mode.
●
●
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these modes and saved in memory. The monitor
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In
addition to the factory preset modes, there are at least twenty user modes that can be entered and
stored.
Energy Saver Feature
When the monitor is in its normal operating mode, the monitor uses less than 47 watts and the Power
light is AquaWhite.
The monitor also supports a reduced power state. The reduced power state will be entered into if the
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and
the power light is turned amber. When the monitor is in the reduced power state, the monitor will
utilize less than 2 watts of power. There is a brief warm up period before the monitor will return to its
normal operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called
power management features).
NOTE: The above power saver feature only works when connected to computers that have energy
saver features.
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to
enter into the reduced power state at a predetermined time. When the monitor's Energy Saver utility
causes the monitor to enter the reduced power state, the power light blinks amber.

The TFT monitor uses high-precision technology, manufactured according to HP standards, to
guarantee trouble-free performance. Nevertheless, the display may have cosmetic imperfections that
appear as small bright or dark spots. This is common to all LCD displays used in products supplied by
all vendors and is not specific to the HP LCD. These imperfections are caused by one or more
defective pixels or sub-pixels.
A pixel consists of one red, one green, and one blue sub-pixel.
●
●
A defective whole pixel is always turned on (a bright spot on a dark background), or it is always
off (a dark spot on a bright background). The first is the more visible of the two.
A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and
only visible on a specific background.
●
To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal
operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm
(20 in).
HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer
cosmetic imperfections and HP will adjust guidelines as improvements are made.
